定点数学库（ QMATH ）包含高度优化的，不动点数学/三角函数是发达国家作为一个易于使用的图书馆，这是关系到用户的应用程序。-Fixed-point math library (QMATH) contains highly optimized, fixed point math/trigonometric functions that are developed as an easy-to-use library, which has to be linked to the user s application. The following table summarizes the set of functions that are defined in this library.

利用itk医学处理包，计算三维图像的峰值信噪比。将图像分块计算不同部位的信噪比，计算的结果将采取文件输出在psnr.txt文件当中，查看结果十分方便。另外还提供了一些三维的实例图片，包括含噪声的和不含噪声的，方便验证算法的正确性。

增量式PID算法，用于调速电机，或者其他控制对象，算法简单，易于移植于单片机中，曾用于飞思卡尔电机调速和巡线算法中。
